New York Rep. Anthony Weiner has retained an attorney to advise him “what civil or criminal actions should be taken” after a lewd picture was sent from his Twitter account.

Weiner, who has represented part of New York City since 1998, says online hacking led to a close-up shot of a man’s underwear being sent from his official Twitter account Saturday night.

Dave Arnold, a spokesman for Weiner, said the Congressman’s staff is “loathe to treat” this incident as more than a prank “but we are relying on professional advice.”

“At a time when the GOP is playing games with the debt limit, a member of the Supreme Court is refusing to recuse himself from matters he has a financial interest in, and middle class incomes are stagnant, many want to change the subject,” Weiner said in a statement emailed to POLITICO by his office. “I don’t. This was a prank, and a silly one. I’m focused on my work.”

Weiner’s office did not answer specific questions about the photograph, whether he has contacted authorities or the Seattle woman who received the photograph. He has said that his Facebook was hacked and if his Twitter had the same password, that too could be vulnerable.

Gennette Nicole Cordova, a college student in Washington state who was allegedly the intended recipient of the photograph, said in a statement to the New York Daily News that she has “never been to New York or to D.C.”

“There have never been any inappropriate exchanges between Anthony Weiner and myself, including the tweet/picture in question, which had apparently been deleted before it reached me,” she said in the statement.
